My 6.0 l96 with 236/246 110 cam and headers trys to stall when I go from reverse or drive to park or neutral. Some times it dies, other times it dips to 4-500 rpm and quickly comes back up. I don't have a log or my tune on hand right now but will post them later.
It goes from p/n to gear perfect just not the other way around. I've tried adding to the air flow min but it just starts bucking really bad, ive tried adding and subtracting from integral air flow, torque follower, and timing.
Cam idles great, just doesn't like going back to park or neutral.
One other problem is my converter unlocks when im cruising and let off. It's just a 60e with circle d 3200 converter. I can only find one table to adjust lock up vs tps and it shouldn't be unlocking.
